Correct vertex input tests on null driver
On Null driver all features are enabled and this triggered execution
of tests for 128 vertex attributes that are not commonly supported.
Tests allocate buffer for verification which is not big enough for
128 attributes. This causes memory corruption and crash.
This change resolves those issues.
